DataSet.DataTable.DataRow（单个）到 XML 字符串

发布于 2025-01-02 02:42:54 字数 508 浏览 0 评论 0原文

我当前正在处理的项目中有强类型数据集，我需要将 DataRow 对象从 DataSet（DataSet 中只有 1 个 DataTable）转换为 XML 字符串。我尝试了以下方法，但完全失败了：

string originalXmlString = string.Empty;

DataSet ds = new DataSet();

ds.Tables.Add(this.ObjectDataRow.Table);
ds.Tables[0].ImportRow(this.ObjectDataRow);

using (StringWriter sw = new StringWriter())
{
    ds.Tables[0].WriteXml(sw);                         
    originalXmlString = sw.ToString();
}

req.OriginalDataRow = originalXmlString;

任何帮助将不胜感激！

谢谢，基思

I have strongly-typed datasets in the project that I am currently working on and I need to convert a DataRow object from the DataSet (only 1 DataTable in the DataSet) to an XML string. I attempted the following with only utter failure:

string originalXmlString = string.Empty;

DataSet ds = new DataSet();

ds.Tables.Add(this.ObjectDataRow.Table);
ds.Tables[0].ImportRow(this.ObjectDataRow);

using (StringWriter sw = new StringWriter())
{
    ds.Tables[0].WriteXml(sw);                         
    originalXmlString = sw.ToString();
}

req.OriginalDataRow = originalXmlString;

Any help would be greatly appreciated!

Thanks,
Keith

我能够在有关 Clone() 函数。

以下代码经过修改并且效果很好：

string originalXmlString = string.Empty;

DataSet ds = new DataSet();

//ds.Tables.Add(this.ObjectDataRow.Table);

ds.Tables.Add(this.ObjectDataRow.Table.Clone());

ds.Tables[0].ImportRow(this.ObjectDataRow);

using (StringWriter sw = new StringWriter())
{
    ds.Tables[0].WriteXml(sw);                         
    originalXmlString = sw.ToString();
}

req.OriginalDataRow = originalXmlString;

I was able to figure it out with the assistance of a MSDN page regarding the Clone() function.

The following code is revised and works great:

string originalXmlString = string.Empty;

DataSet ds = new DataSet();

//ds.Tables.Add(this.ObjectDataRow.Table);

ds.Tables.Add(this.ObjectDataRow.Table.Clone());

ds.Tables[0].ImportRow(this.ObjectDataRow);

using (StringWriter sw = new StringWriter())
{
    ds.Tables[0].WriteXml(sw);                         
    originalXmlString = sw.ToString();
}

req.OriginalDataRow = originalXmlString;
